UNITED STATES JOHN H. MORSE, OF PEORIA, ILLINOIS.

IMPROVEMENT IN COMBINED LATCHES AND LOCKS.

Specification forming part of Letters Patent No. 121,253, dated November 28, 1871; antedated November 18, 1871.

To all whom it may concern:

Be it known that I, JOHN H. MORSE, of Peoria, Peoria county, State of Illinois, have invented certainImprovements in Door-Locks, of which the following is a specification:

The nature of xny invention consists in constructing a metal case, tubular in form, with stays or -ribs upon upper and lower halves for holding it in the door. rlhis case being split in halves from end to end can be opened and a round bolt or latch placed within and operated by a spiral spring, latch, or bolt operated by a knob placed upon a rod, with arms reaching down into the case and taking hold of lugs attached to the bolt. This bolt or latch being attened at the tail end a cross-bar is formed thereon. Within the case and behind the bolt are one or more jawed tumblers, and when used simply as a latch the cross-bar is held by and within the jawsof tuinblers; but if it is desired to be used as a lock, a iIat key, made in proper shape, may be inserted in the key-hole, opening the jaws of tumblers, and the cross-bar will be released from them and the latch will shoot forward by the force of a spiral spring. The key being removed the tumblers will fall down and the bolt be prevented from being withdrawn by the crossbar coming in contact with the tumblers.

Figure 1 is a lock complete; Fig. 2, upper half of lock-case; Fig. 3, perspective view of interior of lock-case; Fig. 4, sectional elevation; Fig. 5, vertical section of lock, door, Sac. 5 Fig. 6, section of lock, showing insertion of key and its action on tumblers; Fig. 7, perspective view of tumblers.

The manner of attaching it to a door is as follows: Into the edge of the door, ata proper height, bore a hole the size and depth of metal case C B, Fig. 1, and back from the edge of door about three inches, and just above the lock, a cross hole to receive the knob-rod b. (See Fig. 5.) Now place the metal case O B containing the bolt and tumblers within this hole, with the hole j in the upper half of case C uppermost, and drive it within a half inch of home. Insert the knob-rod b with its two arms d d turned to the front; turn them down into the case O B through the hole j. (See dotted lines, Fig. 4.) The arms el el will straddle the iiattened part D s of bolt D, and the slots t t in arms d cl will catch the pin f f, as seen in Figs. 3 andv 4, dotted lines. Drive the case O B into the door flush with the edge of door, put on the knobs, and cut the key-hole i, (see Fig. 1,) and the stays m m will hold it in position. The whole is then complete.

What I claim as my invention, and desire to secure by Letters Patent, is-

The form of round bolt D, with its iiattened part D s, piuff, cross-bar g, in connection with tumblers E, all inclosed in a round metal case, O B, with stays m m, and operated with knobrod b, with arms d d, and iiat key F, all Working in the manner and for the purpose herein speci- J. H. MORSE.
